To all whom it may concern:

Be it known that I,- VRnninm BEU'TTEN- a resident of the eil'iv and county of Phil-` adelphia, Stale of Pennsylvania, have in` vented an Improvement in Machine-Tools,y of which the following is a specification;

My invention has reference to machine tools and consists of certain improvements which are fully set` forth in the following specification and shown in the accompanying drawings which form a` part thereof.

The lobject of my invention is to provide a construction of turning-mill orlathe which ehall be adapted for automatically turning the rim of ear wheels, whereby the wheels may be turned to accurate gage and accomplished in u speedy and eliioient manner Withont'requiring any special skill or judgnient on the part of the operator in charge of the' machine. In the preferred form of my invention my improvements are applied to that class of machines4 which are eonnnonly culled turning or boring mills, and having a horizontal turntable rotated under suitable tool holders` and feeding;l mechanism therefor, 'whereby lheovork is rotated against the tools, the machine es a whole` oonetituting in effect a lathe with a'horizontal Face plate. 'While Vprefer chiel character of machine for ohviouel1 reasone when operating upon heavy work, m5" .invention may he employed in tonnention with lathes ot' any character.

In Carrying ont my invention, I provide the two tool holders of thelnill with cutters arranged to operato upon different portions of the flange ol the Wheel, one tool to out from the crown of the flange downwardly aeross the tread of the wheel, While the other ruiter ie adapted to rot from the Crown ot' lhe wheel over the riin and rear faire of the wheel adjacent to the flange portion, and with thoeo entiers I ooniliine former oonlrolling deviene` which causes the cutting' lool4 lo he controlled in their movement .eo ne to inquire the oilitinpjot' lhe flange and (read portion onliv to thix extent roqliwd :oid as dominated in' the Smid h-xnplols or fonia-rss.

automatically under the control ofthe teniplots or formers during the vert-ical adjustnient of said tool holders.-

My lnventlon consists of the improvements which are more fully described hereinal'ter and delinedn the claims.

Referring to the drawings, Figure 1 is a front elevation of a Wheel turning machine embodying my i11v\r1tiox1; Fig. 2 is u sectional plan view'of the Vsaine; Fig. 3 is a` eroseseetion on line .f-- of Fig. 1; Fig. 4 is :t diagramnuilie vlew indicating the relation of the lemplets to the portions of the wheels whioh are to be turned; and Fig. 5 is a sectional plan view of means for adjusting the tool slide. i

2 is the mainframe of the machine, and is provided with the usual rotating turntable il, which may he rotated in any suitable manner.y The main franie is further provided willi the usual upright guides 4 upon which the horizontal' tool holdingr frame is veflioally guided and whorio position vertically may he adjusted hy the usual screws 6'. Upon the horizontal guide 5 .are two side plates which may he respectively odjusted horizontally ulonrr the guide frame 5 by Srrews 28 and 28?'. Eni-.h ot these plates has pivoled upon il tool holding frames 8 which muy he adjusted to dilierent angles in a vertical plane and damped by clamps 8". These tool holding frames are provided with tool holders 9 having the cottimo; tools l() clamped in position at thix bottom` and further heingprovided with a roch ll, which, hy means of' the rie-ml hand wheel and connectinggearinn' l! maylieemployml toadjnst the lool holdex` 9 in :1 more or less verlioal direction upon [he tool holding: lrnmo. Y

All of llio mechanism so tar described may he ronsirler-od as common to anylhoring" or turning mill. y'

l will now flesrrihe. the nierhanism for :wloinalieally vontrolling the horizontal operation ol' lho tools und lool holders, and while ihis nwrhnnisin is Substantially siinilnr Willi resin-vl io oooh ol the tno tool holders, it is adopted toonuso the said lool holders to operato indepomlenlly under the. control ol: separato leon-lois o r 'formel-s.

ltel'urring to the right hund lool holder in Fig. 1, namely, that which is intended to turn the Wheel rim from the crown of the dan e across the tread of the wheel, the tool hol er 9 is provided with a frame 13 bolted to the said tool holder and carrying a roller 14.V This rollel 14 works against the face 15 of the templet 16, and said templet 16 is detachably secured to a rim 17 which is adjustable upon a block 18 in a vertical digection, the said block 18 being clamped l1 on the horizontal guide frame 5 by means o bolts 19. The arm 17 is guided in vertical guides 20 in the frame 18 and is adjusted vertically therein by means of an adg justing screw 21 carried by said frame 18 and working through a screw-threaded aperture in the arm 17. By means of this adjusting mechanism, the vertical position of the former supporting arm may be adjusted and secured. The tool holder mechanism is caused to be moved horizontally by means of a cable 14 extending from the pivoted tool holding slide 18 to the distant end of the horizontal guide frame 5 where it passes over a pulley 22 and connects with an opcrating Weight 23. From this mechanism it. will be understood that if the tool holderl 9 be adjusted from a position downward, the roller 14 will follow the edge 15 of the former 16 and cause the tool 10 to be adjusted horizontally to a greater or 4less extent, so that its cutting position corresponds exactly to the former for every position of vertical adjustment. In this manner the rotation of the work against the tool 10 dur ing the vertical adjustment of the tool holder and tool will canse the Work to be turned in exact accordance to the shape of the former edge 15. The Work in the particular illustration is shownas a car wheel, and the entter and mechanism just described is arranged to operate tovturn the outer working face of the car wheel from the crown of the iange across the tread portion. The left hand tool holding and adjusting mechanism is similar to that above described, but is intended to operate in the opposite direction, so that while the right hand cutter is o crating upon one part of 5 the wheel, the ot er cutter will be operating upon the diametrieally opposite part of the wheel, but the coperation of these cutters will preferably be such that the turning of the two arts, namely above and below the crown ofthe ilange et the wheel will be aecomplished simultaneously, and so co crate' that where the turning of one cutter eaves ...the other begins. In connection with hand cutter, the tool holder is pro V"tf-1de(lWlll u'roller 14; Similar to roller lil, which'A works in connection with :l former 16* havin a Working face l5, This 'former V3.6 is ho ted to an apn 17 ivhieh in turn is guided in vertical guidefsots Q0 upon a hloclLlSl and'whiillrindistment is secured by an adjusting screw 21, The frame or plate 18 1s bolted upon the horizontal guido' frame 5, as in the case of the block 18. 'H1 the adjustment of the lett. hand tool holder* it is arranged vertical or its angle to a vertical line may be the reverse off the tool holder at the right hand side of the machine,V because in this case it is required to-performthe cutting operation over the upper edge of the rim and flange. The two frames 18 'Z5 and 18* may be connected together by means of an adjustable connecting rod Z4 having right and left handed screw-threaded ends which engage the respective nuts 25 and 25* on the blocks 18 and 18, By means of this '80 connecting rod the relative lateral positions of the two formers may be varied and definitely lixed, the said adjustments being to insure the formers heim1r accurately spaced apart to satisfy the ditlerent diameters of the wheels to be turned. After the adjustnient of the formers relatively to each other is secured by means of the connecting rod 9.1, the said frames 18 and 18 are positioned and secured upon the horizontal guide frame 5 and remain in such positions throughout the use of the tool in the repeated turning of successive wheels of the same diameter. The tool holder for the left hand cutter is Caused to be adj usted horizontally to remain in eonl tact with the guiding edge 15L of the former 1G by means of a cable 14.- passing over a pulley 22 and supporting an operating weight 2l-l, corresponding to the similar applianees employed in connection with the right. hand tool holder, but operatingin the reverse direction. To enable adjustment of the slides 7 upon the guide frame 5 by the screw shafts 28 and 28, I may provide the Y said slideswith suitable means of any kind which will temporarily engage the screw shailts such as have been employed in Ina-` chine tools. but in the construction shown l have a square spool 2f) threaded upon the` screw shaft and sliding inthe lug bearing,r 2T no on the back of the slide 7 as .shown in Figs. 3 and 5, the bearing E27 und slide 7 having freedom of play upon the spool. To adjust the slide it is only necessary to rotate its screw shaft Q8 or 28 until thc head of the 115 spool strikes the end of the bearing 27 after which a further rotation of the shaft will move the slide. When the slide is rcperly ositioned in relation to the wol-ht e spool 1s readjusted so as to give the slide all the freedom of play necessary, the amount ofj which is dependent u on the horizontal" travel of the slide an tool holder under the control of the formers 16 and 16. Any other means than that shown may be employed for adjusting the slides preliminary lo their automatic movements under the control ot' the formel-s.

My invention may be applied to various cominci-cial types and turning mills and lathes, and l therefore do not restrict myself to any particular form of such machines, nor to the combined use of the two tool holders and forniers controlling devices, as either'of the said devices may be used separately.

While l prefer ,the construction herein set out l' do not limit myself to the details thereolg ways without departing from the spirit of my invention. j

Having now described my invention, what I lclaim as new and desire to secure by Leti ters Patent., is
